Dual Connectivity Data Split Prediction for Coverage Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual-connectivity wireless communication systems, the data-split ratio can result in a majority of the data flow being directed to a secondary connection that is significantly weaker than the primary connection, leading to sub-par user experience due to inadequate coverage strength.
Innovation Solution
A computing system predicts whether the data split will predominantly use the secondary connection and assesses the coverage strength comparison between the primary and secondary access nodes, deciding whether to establish the secondary connection based on these predictions to ensure optimal data flow distribution.

If dual-connectivity is established with a secondary access node, then data capacity is improved, but coverage strength deteriorates when the secondary connection is significantly weaker than the primary connection
Solution Approach 1:
The system performs preliminary prediction of the data-split ratio before establishing dual-connectivity. By predicting whether the data split will predominantly use the secondary connection and comparing this with predicted coverage strength, the system proactively prevents establishing a secondary connection that would result in poor user experience, thereby avoiding the contradiction before it occurs
Solution Approach 2:
The system uses prediction feedback mechanisms to assess both the data-split ratio and coverage strength comparison before finalizing dual-connectivity establishment. This feedback loop allows the system to make informed decisions about whether to proceed with adding a secondary connection, balancing data capacity gains against potential coverage strength deterioration

AI summary
A mechanism for controlling configuration of dual connectivity for a user equipment device (UE), where the dual connectivity includes the UE being served cooperatively by (i) a first access node over a first air-interface connection between the UE and the first access node and (ii) a second access node over a second air-interface connection between the UE and the second access node. An example method includes (a) predicting whether both (i) in the dual connectivity, a data split will put a threshold greater portion of data flow of the UE on the second air-interface connection than on the first air-interface connection and (ii) coverage strength of the UE from the second access node will be threshold lower than coverage strength of the UE from the first access node and (b) using the prediction as a basis to control whether or not to establish the dual connectivity for the UE.
